Description
Die Erfindung betrifft eine Spannschrauben-Anordnung für Spannelemente zur kraftschlüssigen, keil-und spielfreien Verbindung von Rotationskörpern mit einer Welle.The invention relates to a tensioning screw arrangement for tensioning elements for a non-positive, wedge-free and backlash-free connection of rotating bodies with a Wave.
Es sind bereits Spanneinrichtungen bekannt, bei denen die Ringfedern-Spannelemente durch eine oder zwei zentral angeordnete Spannmuttern axial beaufschlagt werden, um dadurch den Radial-Kraftschluß (Preßsitz) zwischen Nabenkörper und Welle zu erzeugen. Auch ist bekannt, statt der Spannmutter eine zentral in der Welle sitzende Spannschraube zu verwenden. Ferner ist die Verwendung von Lehrfach-Spannschrauben die planetenartig im nabenkörper sitzen bekannt, die über Druckringe die Spannelemente axial beaufschlagen. Diese bekannten Spanneinrichtungen genügen nicht den Ansprüchen, die für die Praxis erforderlich sind. Es ist nachteilig, daß für die Spannmutter entweder an der Welle ein Gewindeansatz sein oder im Nabenkörper selbst ein Gewinde eingeschnitten werden muß. Bei der bekannten Mehrfach-Spannschrauben-Anordnung müssen Gewindelöcher in der Nabe gebohrt und zur Druckübertragung entsprechende Druckringe gefertigt werden « In jedem Fall sind zusätzliche Arbeiten entweder an der Welle oder an der Nabe des Rotationskörpers auszuführen. Auch ist es baulich nicht immer möglich, die Spanneinrichtungen raumsparend unterzubringen. Der größte Nachteil der bekannten Spanneinrichtungen ist der, daß bei mehreren hintereinandergeschalteten Spannelementen und bei einseitiger Spannung durch die Reibungsgesetze bedingt, nach hintenzu ein Kraftschlußabfall zu verzeichnen ist. Durch diese Tatsache können bei einseitiger Spannung für die Drehmomentaufnahme nutzbringend im besten Fall nur vier Spannelemente angeordnet werden, da ein fünftes Spannelement fast keine Radialpressung mehr hergibt.Tensioning devices are already known in which the annular spring tensioning elements are axially loaded by one or two centrally arranged clamping nuts, in order to generate the radial frictional connection (press fit) between the hub body and the shaft. It is also known to have a clamping screw seated centrally in the shaft instead of the clamping nut to use. Furthermore, the use of subject tensioning screws is planet-like Sitting in the hub body is known to act on the clamping elements axially via pressure rings. These known clamping devices do not meet the requirements for practice required are. It is disadvantageous that either on the shaft for the clamping nut be a thread approach or a thread can be cut in the hub body itself got to. In the known multiple clamping screw arrangement, threaded holes must be in The hub is drilled and corresponding pressure rings are manufactured for the transmission of pressure “In any case, additional work is either on the shaft or on the hub of the solid of revolution. It is also not always structurally possible to use the clamping devices to be accommodated in a space-saving manner. The main disadvantage of the known clamping devices is the fact that with several clamping elements connected in series and with one-sided Tension caused by the laws of friction, towards the rear a loss of frictional connection is recorded. Due to this fact, in the event of unilateral tension for the In the best case scenario, only four clamping elements are advantageously arranged because a fifth clamping element gives almost no more radial pressure.
Durch die vorliegende Erfindung werden die Nachteile der bekannten Spanneinrichtungen beseitigt und weitere Vorteile erzielt. Das Hauptmerkmal der Erfindung ist darin zu sehen, daß die Spannelemente selbst in Ihrem mittleren Ringdurchmesser planetenartig angeordnete Spannschrauben besitzen. Dadurch, dab jedes Spannelement seine eigene Spanneinrichtung hat, wird erreicht, daß an Welle und Nabenkörper keine zusätzlichen Arbeiten für die Verspannung der Spannelemente ausgeführt werden müssen, so daß die Wellen und Bohrungen der Naben glatt zylindrisch bleiben können. Ein weiterer großer Vorteil ist darin zu sehen, daß auch bei einseitiger Spannmöglichkeit und mehreren hintereinander angeordneten Spannelementen, jedes Spannelement nunmehr einen 100% Kraftschluß ermöglicht, so daß es möglich ist, größte Drehmomente zu übertragen. Leiter können nunmehr beliebig viele Spannelemente ohne Kraftschlußabfall eingebaut werden, wenn die Konstruktionsaufgabe es erfordert. Auch können die einzelnen Spannelemente mit unterschiedlichem Kraftschluß verspannt werden, wenn es für die Konstruktion zweckdienlich ist. Erfindunggemäß sind nunmehr alle Variationen eines lösbaren Preßsitzes von Rotationsteilen mit der Uelle gegeben. Ferner können die Spannelemente mit Spannschrauben komplett in größeren Serien wirtschaftlich gefertigt werden, In der Zeichnung sind usführungsbeispiele der Erfindung in sechs Abbildungen dargestellt.The present invention eliminates the disadvantages of the known Clamping devices eliminated and other advantages achieved. The main feature the invention can be seen in the fact that the clamping elements themselves in your middle Have ring diameter clamping screws arranged like a planet. Thereby, that Each clamping element has its own clamping device, that is achieved on the shaft and hub body no additional work for bracing the clamping elements must be carried out so that the shafts and bores of the hubs are smoothly cylindrical can stay. Another great advantage can be seen in the fact that even with unilateral Clamping option and several clamping elements arranged one behind the other, each Clamping element now enables a 100% frictional connection, so that it is possible to use largest To transmit torques. Heads can now have any number of tensioning elements without Loss of adhesion can be installed if the design task requires it. The individual clamping elements can also be clamped with different frictional connections when it is appropriate for the construction. According to the invention are now given all variations of a releasable press fit of rotating parts with the Uelle. Furthermore, the clamping elements with clamping screws can be produced completely economically in larger series are manufactured, In the drawing are exemplary embodiments of the invention in six Illustrations shown.
